WYYG GPU Waterblock RTX 4080 AIC Reference Edition Liquid Cooler

SKU CH-SKD0-2NQYG

Full-cover liquid cooling block for RTX 4080 AIC Reference Edition cards, cooling GPU, MOS and RAM with .5 mm micro-channels.

  • TypeLiquid Cooling System
  • Full-cover cooling for GPU, MOS and RAM
  • 5 mm micro-channel copper base maximises heat transfer
  • 16 mm OD rigid-tube fittings included, 14 mm OD fittings available on request
  • 5 V 3-pin ARGB lighting with remote and hub
  • Inlet and outlet rotatable for flexible loop routing

Targeted Compatibility

This full-cover GPU waterblock is built exclusively for the NVIDIA RTX 4080 AIC Reference Edition PCB. It directly cools the GPU core, memory modules and voltage regulators in a single block. Buyers must verify their card matches the reference layout before ordering, as the block will not fit partner designs with different component placement.

Micro-Channel Cooling Headroom

A 0.5 mm micro-channel injection design spreads coolant across the cold plate for high thermal transfer even with modest pump flow. The large internal flow path keeps restriction low so the loop remains responsive. Builders pushing extreme voltage or sustained compute loads should confirm the block’s thermal limits match their target overclock.

Rigid-Tube Fitting Requirement

Two nickel-plated brass compression fittings for 16 mm OD hard tubing are included in the box; 14 mm OD fittings are available on request after purchase. The block’s G1/4 ports accept standard fittings, but the supplied hardware locks the loop to 16 mm rigid tube unless swapped. Installers planning soft tubing or a different outer diameter must source alternate fittings separately.

Questions about this item

Will this waterblock fit alongside my existing 14 mm OD hard‑tube loop?

Two G1/4 nickel‑plated brass compression fittings for 14 mm OD rigid tubing are included, so it connects directly to your current loop.

How can I confirm the 0.5 mm micro‑channel block is cooling the GPU, MOS and RAM after installation?

Monitor core, memory and VRM temperatures under load; they should drop sharply compared with air cooling, and the RGB LEDs will light when the 5 V 3‑pin header is powered.

What comes in the box and what must I source separately?

The package contains the full‑cover copper waterblock, metal backplate, two 14 mm compression fittings, RGB LED strip, remote control and integration hub; you still need coolant, pump, reservoir, radiator and tubing.
